Hardware Design Services (IoT devices design)
With many years of experience in circuit design (PCB), embedded computers, battery-powered low-power circuit design (Battery), serving IoT applications, smart products operating in industrial environments .
Our service will help customers design products professionally and aesthetically, stably and economically.
Professional and aesthetic circuit design
Complying with design and manufacturing standards, ensuring the design can be processed at any SMT factory in Vietnam or internationally.
The product is stable, easy to maintain and replace
With many years of experience in designing and constructing actual deployed products, the designs of epcb.vn will minimize errors during installation and operation.
Product development cost savings
Selecting the optimal component list (BOM list), the circuit can be made and run immediately, without having to redesign many times to help customers save time, cost of prototype circuit (Prototype), and ensure the progress.
Items of circuit design (PCB):
- Professional Placement and Routing.
- BOM list (parts list) with the most optimal cost.
- Standards-compliant design: DFM (Design For Manufacturing) and DFA (Design for Assembly) ensure SMT and easy repair.
- Design compliance with EMI, EMC.
- Advanced board design: Stackup design, Impedance control, Differential pair, RF...
